If the perpendicular bisector of one side of a triangle goes through the opposite vertex, then is the triangle ( sometimes, alwa

ys, or never) isosceles

It is always isosceles because it can be proved as follows:

The perpendicular bisector dissects the triangle into two, and it is the common side.  Then each side of the bisector is 90 degrees, and the bisected to two equal sides, so the two dissected triangles are congruent, hence the original triangle is isosceles.

Answer:

Then the total area is  116 cm^2 which agrees with answer D

Step-by-step explanation:

Notice we need to calculate the area of two rectangles (one larger at the bottom and a smaller one on top)

The Area of a rectangle is the product: base x height

In our case :

Area of Big rectangle = 12 cm x 7 cm = 84 cm^2

Area of smaller rectangle = 8 cm x 4 cm = 32 cm^2

Then the total area is: 84 cm^2 + 32 cm^2 = 116 cm^2

7y - 3x = -5
-3x = -7y - 5

On the day that Ramon is born, his grandfather deposited $5000 for him in a certificate of deposit paying 10% interest compounde
kkurt [141]

The time required to get a total amount of $1,000,000.00 with compounded interest on a principal of $5,000.00 at an interest rate of 10% per year and compounded 1 times per year is 55.59 years.

<h3>Given data</h3>

Principal = $5,000

Rate = 10%

Final Amount A= $1,000,000

Time = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 10/100

r = 0.1 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(1,000,000.00/5,000.00) / ( 1 × [ln(1 + 0.1/1)] )

t = ln(1,000,000.00/5,000.00) / ( 1 × [ln(1 + 0.1)] )

t = 55.59 years

(about 55 years 7 months)
